I just received a replacement for a failed Catalyst 3508G. I want to prohibit all access to vty lines and only the switch to be managed from the console port.


I have mental block on how I did this in the past. Can someone provide me a hint?

You could add "transport input none" under line vty 0 15.

That was too simple. Why didn't I remember that in the first place. :)

Under the VTY lines, enter no login or no login authentication [your method name].

It seems intuitive that no login would prevent access. But it does not work that way. no login would only supress the prompt for passwords and would not prevent access to the vty. The alternative to transport input none would be to configure no exec on the vty lines.
